Description

Adjustment devices and processing systems

technical field

The present invention relates to an adjusting device adapted to be driven in rotation about a longitudinal axis for adjusting a cutting tool, comprising a supported cutting tool carrier element for performing the adjusting movement, a drive unit for driving the cutting tool carrier element and A circuit-carrying element of the surface area of the drive unit for forming at least one electronic control circuit provided to control the drive unit.

The invention further relates to a cutting system comprising a cutting tool, an adjustment device operatively connected to the cutting tool to adjust the cutting tool, and a rotatably driven main drive element operably connected to the adjustment device to provide machining motion of the cutting tool.

Background technique

According to the prior art shown in FIG. 1 of DE 44 31 845 A1, a machining system of the type described above comprises a lowerable, movable main drive element 14 which is rotatable about a longitudinal axis 12 and clamped on its tool holder 16 There are adjustment devices 18 of the type described above. The adjustment device 18 has a cutting tool carrier element 24 which can be moved by a motor in the direction of the double arrow 22 and has a tool holder 26 for a cutting tool 30 fitted with a cutting insert 28 . When the main drive element 14 is rotated about the longitudinal axis 12, and thus the adjustment device 18 is rotated about the longitudinal axis 12, the cutting blade 28 is moved in a circular path relative to the longitudinal axis 12 according to the radial adjustment set by the motor, and in this way can be connected with the longitudinal axis 12. The workpieces to be machined engage, for example, in order to create or enlarge holes in them. The diameter of a circular path is often referred to as the flight circle diameter. By mounting the cutting tool carrier element 24 to perform the adjustment movement, the flying circle diameter can be changed by the motor in the direction of the double-headed arrow 22 . Thereafter, different radially spaced inner and/or outer regions of the workpiece can be machined with respect to the longitudinal axis 12, so that, for example, different bore diameters can be realized. In particular, the flying circle diameter is adjusted accordingly by electrical adjustment of the cutting tool carrier element 24, and the adjustment device 18 can be used to compensate for cutting edge wear in order to maintain the preset machining diameter.

The adjustment device 18 or the machining system requires a relatively large installation space, in particular in the direction of the longitudinal axis 12 , ie in the axial direction. This is disadvantageous because it reduces the stability of the main drive element 14 , ie in particular the tool spindle, and at the same time it reduces the working space, especially in the case of machining stationary clamped workpieces.

It is therefore an object of the present invention to provide an adjustment device of the above-mentioned type and a machining system of the above-mentioned type, each of which enables an improved compact design, thereby better avoiding instability of the main drive element, in particular the tool spindle, As well as better use of processing installation space.

SUMMARY OF THE INVENTION

For the adjustment device, this task is solved according to the adjustment device of claim 1 . The dependent claims indicate advantageous further embodiments.

Adjustment device adapted to be driven in rotation about a longitudinal axis for adjusting a cutting tool, comprising a supported cutting tool carrier element for performing the adjusting movement, a drive unit for driving the cutting tool carrier element and having a surface facing the drive unit A circuit-carrying element of an area for forming at least one electronic control circuit provided to control the drive unit, wherein two surface points of the surface area are arranged to be connected by a straight connecting line on the outside of the circuit-carrying element, which The endpoints are two surface points. The fact that the two surface points of the surface area are arranged to be connected by a straight connecting line on the outside of the circuit-carrying element, the ends of which are two surface points, means that the circuit-carrying element can be used to control the drive unit in the circumferential direction of the drive unit. The circuit-carrying element, which can preferably be in the form of a printed circuit board, in particular a multilayer printed circuit board, can control the drive unit in the circumferential direction of the drive unit, for example in the drive unit (in particular the planetary gearbox or the main gearbox ) in the region of the gearbox and/or in the region of the shaft element of the drive unit (in particular of the gearbox shaft element and/or of the motor shaft element) and/or in the region of the motor of the drive unit (in particular of the electric motor). Thus, in particular when the circuit-carrying element is arranged in the housing and/or the base body of the adjusting device, in particular the axial dimension of the circuit-carrying element and thus the adjusting device is also reduced. Thus, in particular the total torque acting on the main drive element (in particular of the tool spindle) is reduced by the adjustment device, to which the main drive element can be connected. In this way, the tool spindle can operate at higher speeds, resulting in shorter machining times for more cost-effective machining operations, i.e. higher stock removal rates. Through the fact that two surface points of the surface area are arranged to be connected by a straight connecting line on the outside of the circuit-carrying element, the endpoints of which are the two surface points, the circuit-carrying element correspondingly shortens the axial configuration, especially when the circuit-carrying element is arranged In the housing and/or base body of the adjustment device, the maximum usable distance between the fixed, clamped workpiece to be processed and the adjustment device is advantageously increased, so that the dimensional measurement in the clamped state of the workpiece, Larger workpiece axial dimensions are available. Thus, workpieces of different sizes and workpiece contours for which these workpieces are inaccessible can be machined in a better manner due to the associated larger machining space, especially if the adjustment device is arranged in the machining center.

Since two surface points of the surface area can be connected by connecting straight lines on the outside of the circuit-carrying element, the endpoints of which are the two surface points, the circuit-carrying element can also be formed (in particular by recesses) as a curvature with respect to the longitudinal axis, thus being formed around the Unbalance caused by the rotation of the longitudinal axis of the adjustment device is reduced. Because of the shape of the surface area, ie this connecting line (whose endpoint is the two surface points) extends beyond the circuit-carrying element, the mass of the circuit-carrying element can be arranged more uniformly or at least more uniformly with respect to the longitudinal axis. Thus, the fact that the mass distribution of the circuit-carrying element is more uniform with respect to the longitudinal axis with respect to the circumferential direction of the drive unit offers particular advantages. Accordingly, the circuit-carrying element can preferably be formed as a hollow cylinder or preferably in the form of a plate, in particular a printed circuit board with a recess, the longitudinal axis partially extending into the hollow cylinder or the recess, in particular the hole. In the case of a hollow cylinder, a straight connecting line whose endpoints are two surface points, for example, connects two diameter surface points inside the hollow cylinder to each other. In the case of a plate (ie in particular of a printed circuit board), a straight line whose endpoint is two surface points joins the two surface points, for example, the two surface points are radially delimited (ie in particular the holes of the circuit-carrying element) of the inner wall) of the surface point of the recessed surface. In both cases, the volume of the installation space of the adjustment device is reduced in a particularly simple manner, and at the same time any unbalance which may be caused by the circuit-carrying element when it is rotated about the longitudinal axis is reduced.

The fact that two surface points of the surface area can be connected by a connecting line on the outside of the circuit-carrying element, the end points of which are the two surface points, increases the axial and radial accessibility of the adjustment device. Thus, the adjustment device can be provided in a particularly simple and thus cost-effective manner, for example in the case of adjustment of the adjustment device or in the case of replacement (eg the drive unit or its components).

Due to the fact that two surface points of the surface area can be connected by connecting straight lines on the outside of the circuit-carrying element, the endpoints of which are two surface points, the size of the adjustment device can be reduced and thus its material can be reduced, especially when the circuit When the carrier element is arranged in the housing and/or the base body of the adjustment device, the housing or the base body can be made shorter and therefore lighter without impairing its function. Due to the shortened axial configuration of the circuit-carrying element, the mass of the adjustment device can thus be reduced at the same time, which has a positive effect on the stability of the main drive element, in particular the tool spindle.

In this regard, it is expressly stated that the circuit-carrying element may preferably be monolithic, eg comprising one (in particular multilayer) substrate, especially in the form of a printed circuit board, or preferably modular, eg comprising multiple A number of substrates, in particular a number of printed circuit boards, are detachably connected to each other. The former is preferably favorable for flexural strength, and the latter is preferably favorable for structural design freedom.

Since the circuit-carrying element is shaped to form an electronic control circuit, the circuit-carrying element is particularly suitable for electrical conductor tracks provided on and/or in the circuit-carrying element, eg, between two circuit-carrying element layers of the circuit-carrying element, and/or Depending on the circuit, the circuit-carrying element can be assembled and/or have at least one electronic component (eg a microchip, a resistive element, a capacitor or an induction coil).

A control circuit, in particular, a control circuit suitable for activating the drive unit in a preset manner based on one or more input signals, ie, for example, in order to set the motor, in particular the electric motor of the drive unit, into a state of energy flow.

Preferably, the circuit-carrying element already includes the control circuit. Even more preferably, the circuit carrying element has means (eg comprising at least one electronic connection element) for receiving at least one input signal. Even more preferably, the circuit-carrying element comprises means (eg comprising at least one microchip) for processing at least one input signal according to data. Even more preferably, the circuit-carrying element has means for transmitting to the drive unit at least one input signal, whether in data-processed form and/or data-unprocessed form.

The surface area of the circuit-carrying element facing the drive unit preferably refers to the surface area of the drive unit which can be connected to the circuit-carrying element by means of a calibration line, the two ends of which are located on the drive unit and the circuit-carrying element, the calibration line at these two. The different surface areas extend beyond the circuit-carrying element. The calibration line can be located on the calibration plane, the normal vector of the calibration plane includes the calibration angle with the longitudinal axis, and the calibration angle is greater than or equal to 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40° °, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85° and less than 90°. The calibration angle is preferably 0°, whereby the orientation of the calibration plane is perpendicular to the longitudinal axis, so that the unbalance induced by the circuit-carrying element can be reduced in a particularly optimized manner, ie in each case relative to the longitudinal axis radial and axial.

Extending outside the circuit-carrying element means in particular that the connecting line between two surface points extends or extends beyond the solid-substance region of the circuit-carrying element. This is especially the case if this connecting line extends or extends within a recess of the circuit-carrying element, in particular of a hole.

In this regard, it is expressly stated that for the purposes of this disclosure, unless otherwise stated, the term "longitudinal axis" should be understood in a geometrical sense. Particularly preferably, the longitudinal axis is or can be aligned with the axis of rotation of the main drive element (in particular of the tool spindle).

In particular, the adjustment means are shaped to extend along the longitudinal axis. Preferably, the longitudinal axis is located inside the adjustment device.

The surface area of the circuit-carrying element facing the drive unit may preferably consist of one or more curved individual surface areas of the circuit-carrying element. Alternatively or additionally, the surface area of the circuit-carrying element facing the drive unit consists of a plurality of planar surface areas, which are arranged at an angle to each other, for example, according to each case, an inner surface angle of 90°, 95°, 100° °, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170° or 175°. The plurality of planar surface portions may preferably be arranged in pairs, each pair forming a right angle, ie an inner surface angle of 90°. It is conceivable and also possible that the surface area of the circuit-carrying element facing the drive unit consists of the aforementioned curved and planar surface areas.

The surface area of the circuit-carrying element facing the drive unit is preferably the surface area first formed by the recess in the circuit-carrying element. This is a cost-effective measure and it saves installation space.

Viewed in the direction from the drive unit to the circuit-carrying element, the surface area of the circuit-carrying element facing the drive unit is preferably visible as a concave surface area of the circuit-carrying element. This measure further reduces the imbalance caused by the circuit-carrying element and at the same time reduces the volume of the adjustment device installation space. Particularly preferably, the surface area facing the drive unit is hemispherically concave when viewed in the direction of the drive unit.

In the sense of the present disclosure, the drive unit is arranged to drive the cutting tool carrier element so that it performs the adjustment movement. For this purpose, the drive unit comprises, for example, a motor, in particular an electric motor, with a motor shaft. More preferably, the motor shaft is operatively (in particular by means of a gear connection) connected to a gearbox (particularly preferably comprising a gearbox output shaft), wherein, in the gearbox driven state, the rotational speed n1 of the gearbox output shaft is less than The rotational speed n2 of the motor shaft, according to which the gearbox is designed as a reduction gearbox. In this way, a particularly precise adjustment of the cutting tool carrier element can be provided. Preferably, the motor shaft speed n2 is at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000 times or more. This measure makes it possible to use in a particularly advantageous manner compact, high-speed electric motors (for example in the field of toy construction).

The adjustment movement is preferably linear, as this is particularly useful for drilling holes, for example. Even more preferably, the adjustment movement is also linear in translation.

The adjustment movement is preferably radially oriented or orientable, ie in particular transverse to the longitudinal axis. Preferably, the adjustment movement can be assigned a corresponding (in particular a maximum reachable distance) radial distance of less than or equal to 100 mm, 95 mm, 90 mm, 85 mm, 80 mm, 75 mm, 70 mm, 65 mm , 60mm, 55mm, 50mm, 45mm, 40mm, 35mm, 30mm, 25mm, 20mm, 15mm, 10mm, 9mm, 8mm, 7mm, 6mm, 5mm, 4 mm, 3 mm, 2 mm, 1 mm, 0.9 mm, 0.8 mm, 0.7 mm, 0.6 mm, 0.5 mm, 0.4 mm, 0.3 mm, 0.25 mm, 0.2 mm, 0.15 mm, 0.1 mm, 500 microns, 400 microns, 300 microns, 100 microns, 50 microns, 25 microns, 10 microns, 5 microns, 1 micron, 0.5 microns or 0.25 microns. These are particularly useful adjustment ranges when machining metal workpieces.

Preferably, the drive unit is arranged to perform in linear step increments equal to 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 or 0.5 microns Adjust the movement. This can also be expressed in terms of corresponding rotational angle increments of the gear shaft.

Preferably, the drive unit is designed to be self-locking, so that in the non-driven state of the drive unit, preferably in the radial direction, the adjustment position of the tool carrier element is constant, ie in particular with respect to the longitudinal axis of the tool carrier element The radial distance remains constant. This advantageously provides precise chip removal machining by means of the adjustment device when the cutting tool is connected to the cutting tool carrier element.

Preferably, the cutting tool carrier element is designed for reversibly releasable fastening of the cutting tool. Preferably, at least one mechanical fastening element, in particular a threaded element, is then provided, which can be reversibly releasably connectable with at least one threaded element of the cutting tool carrier element. This measure makes changing the cutting tool particularly easy.

The circuit-carrying element preferably has at least one electrically insulating layer or more preferably two insulating layers, eg a plastic comprising (in particular cured plastic). In the case of at least two insulating layers, one or more electrical conductor tracks (preferably comprising copper or its alloys or gold or its alloys or silver or its alloys) are preferably arranged and/or can be arranged at least between two adjacent insulating layers. Similarly, in the case of an insulating layer, the material of the electrical conductor track (or tracks) is selectable, wherein the electrical conductor track (or tracks) are arranged and/or can be arranged on its surface .

Even more preferably, the circuit-carrying element has a placement recess (preferably of a hole) in which an electronic contact element with one or more components for forming an electronic control circuit can be arranged, preferably in an at least partially form-fit manner, in order to In this way they are connected to the circuit-carrying element and its one or more electrical conductor tracks by one or more solder connections.

Preferably, the circuit-carrying element already has an electronic control circuit, for example by equipping the circuit-carrying element with a microchip. This is a particularly advantageous measure, according to which the control of the drive unit is provided at particularly low cost. For the formation of the electronic control circuit, at least one resistive element, at least one capacitor or at least one electrical coil, in particular at least one induction coil, can also be considered as an alternative or supplement.

Preferably, the adjustment device includes a control assembly having a circuit-carrying element, more preferably the control assembly includes a circuit-carrying element having an electronic control circuit formed thereon. Preferably, the control assembly is arranged to activate the drive unit in a preset manner (eg by means of a circuit-carrying element comprising receiving and signal processing means).

The cutting tool carrier element may preferably be plate-shaped, wherein the support plate of the cutting tool carrier element has a contact surface provided with grooves which engage and/or engage with the contact surface of the (in particular U-shaped) cutting edge seat of the cutting tool Can be engaged, the shape of its contact surface corresponds to that of the support plate. A preferably U-shaped cutting edge seat and its corresponding cutting edge which may be included in the adjustment device and optionally form a cutting tool, the cutting edge may be included in the adjustment device and have at least one cutting edge and its associated free surface and With its associated rake face, the cutting tool can be a milling cutter, drill, reamer or other cutting tool, depending on the shape of the cutting edge seat and the geometry of the cutting edge. It is also conceivable and possible to provide multiple cutting edges in and/or on the cutting tool.

According to a further embodiment of the adjustment device, the connecting line passes through the drive unit. The drive unit can thus be surrounded at least partially by the circuit carrier element particularly tightly in the tangential direction. This further reduces the installation space volume of the adjustment device, especially in the axial direction, as well as the imbalance caused by the circuit-carrying element. By penetration, preferably it is meant that the connecting line enters from one point of the drive unit in the geometrical sense and exits from another point of the drive unit in the geometrical sense. Preferably, the two points are arranged diametrically opposite each other. Preferably, the connecting line penetrates the drive unit, for example in the region of the gearbox of the drive unit (in particular of the planetary gearbox or main gearbox) and/or of the drive unit (in particular of the gearbox shaft element and/or of the motor shaft element) ) motors of shaft elements and/or drive units, in particular of electric motors.

It is conceivable and also possible for the connecting line to be tangential to the drive unit, for example in the region of the gearbox of the drive unit (in particular of the planetary gearbox or of the main gearbox) and/or of the drive unit (in particular of the gearbox shaft elements and (of the motor shaft element) and/or the motor of the drive unit (in particular of the electric motor). This is a critical case where the cable penetrates the drive unit. This is another way to save installation space. However, it is also conceivable and possible that this limit case does not apply.

According to another embodiment of the adjustment device, the drive unit is arranged to execute in at least part of the recess of the circuit-carrying element. Accordingly, the circuit-carrying element has recesses that can be obtained (for example by drilling and/or milling), wherein the surface area of the circuit-carrying element facing the drive unit is the circuit that radially delimits the recess, ie in particular of the inner wall of the hole The surface area of the surface that carries the element. Thus, the drive unit can be at least partially surrounded by the circuit-carrying element more closely in the tangential direction, which further correspondingly reduces the installation space volume and the imbalance that can be induced by the circuit-carrying element. The recesses may preferably be assigned to two openings of the circuit-carrying element, the two openings being connected to each other in communication with each other and through which parts of the longitudinal axis extend. The shape of the opening is preferably circular or polygonal.

It is expressly stated here that the recess of the circuit-carrying element can be a closed annular shape, which can be obtained (for example) by drilling and/or milling in a feed direction parallel to the longitudinal axis, or open in a radial direction, (for example) It can be obtained by drilling and/or milling in the feed direction parallel and transverse to the longitudinal axis. The annularly closed recess reduces imbalances which can be caused by the circuit-carrying element in a particularly advantageous manner. The radially open recess enables a particularly advantageous radial mounting of the circuit-carrying element by allowing the circuit-carrying element to be pushed laterally to the drive unit.

Particularly preferably, the recesses in the sense of the present disclosure are circular, and the coordinates of the center of the recesses (especially in the circuitless state) correspond to the preferably two-dimensional barycentric coordinates of the circuit-carrying element. In this way, unbalances which can be induced by the circuit-carrying element are reduced in a particularly optimal manner.

Preferably, the planar surface portion of the circuit-carrying element adjacent to the recess may be assigned a normal vector oriented parallel to the longitudinal axis. Accordingly, the orientation of the circuit-carrying element at least in the region of the surface portion is perpendicular to the longitudinal axis, which saves the installation space volume.

According to another embodiment of the adjustment device, the recess is delimited by a circumferentially closed edge of the circuit-carrying element, which preferably provides a circumferentially closed (preferably annular) recess, so that the circuit-carrying element is correspondingly in the circumference of the drive unit. Surrounding the drive unit in a circumferentially closed manner in the radial direction, for example in the region of the gearbox of the drive unit (in particular of a planetary or spur gearbox) and/or of the drive unit (in particular of the gearbox shaft element and/or the motor) of the shaft element) and/or of the motor region of the drive unit (in particular of the electric motor). The circumferential closed edge can be obtained in particular by drilling and/or milling the circuit-carrying original body element. This further correspondingly reduces the installation space volume and the unbalance that can be induced by the circuit-carrying elements, in particular since this enables a rotationally symmetrical arrangement of the circuit-carrying elements with respect to the longitudinal axis. Thereafter, the circumferential closing edge is preferably rotationally symmetric, and the longitudinal axis is the corresponding axis of rotational symmetry. The circumferential closed edge may preferably be circular or polygonal, ie preferably square, rectangular, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon or decagon. Preferably, in the case of polygonal recesses, corners, ie transitions between two adjacent surface areas, can be characterized by means of finite radii of curvature, so that these transitions are continuously shaped. More preferably, the polygonal recesses are equilateral.

Preferably, the center of gravity of the circuit-carrying element is arranged within the recess. Thus, the circuit-carrying element is balanced or at least substantially balanced, which advantageously increases the mobility of the adjustment device.

Preferably, the circuit-carrying element is shaped like a plate. This is a particularly advantageous measure since it further reduces the installation space volume. In addition, the circuit-carrying element is preferably designed as a circular, (especially multilayered) printed circuit board, more preferably, along its outer circumference. If the circuit-carrying element is formed in a plate-like shape, it can be assigned a preferably constant plate thickness, in order to reduce the risk of collisions during assembly of the circuit-carrying element while saving the installation space volume.

According to another embodiment of the adjustment device, the largest longitudinal dimension of the circuit-carrying element measured parallel to the longitudinal axis is less than or equal to the largest lateral dimension of the circuit-carrying element measured parallel to the transverse axis, wherein the transverse axis is oriented perpendicular to the longitudinal axis. This further reduces the installation space volume especially in the direction of the longitudinal axis. In the case of a circuit-carrying element of plate-like design, this can be achieved by a corresponding inclination of the circuit-carrying element with respect to the longitudinal axis, or (more preferably) a perpendicular orientation with respect to the longitudinal axis.

According to another embodiment of the adjusting device, a motion converter is provided for converting the motion of the moving element of the drive unit into an adjusting motion, the motion converter can be kinematically coupled to the cutting tool carrier element and the drive unit. In this way, a movement (eg rotational movement) of the moving element provided by the drive unit can be converted into an adjustment movement (in particular linear and oriented transversely with respect to the longitudinal axis) in an advantageous manner, wherein the moving element can be the driving The gear output shaft of the gearbox of the unit (in particular of a planetary gearbox or spur gearbox) and/or the motor shaft of the (eg of a pinion) motor of the drive unit (in particular of an electric motor). Particularly preferably, the motion converter is designed as an eccentric gear, with which the rotational movement of the gear output shaft of the gear of the drive unit (in particular of a planetary or spur gear) and/or of the drive unit (in particular of an electric motor) The motor shaft of the motor (eg of the pinion), the rotational movement can be converted into an adjustment movement, in particular a linear and transversely oriented movement with respect to the longitudinal axis. Particularly preferably, the motion converter is arranged adjacent to the circuit-carrying element, since this further increases the compactness of the adjustment device.

Preferably, the motion converter is kinematically coupled to the drive unit, so that in the non-driven state of the motion converter, the adjusted position of the cutting tool carrier element (preferably in the radial direction, ie transverse to the longitudinal axis) can be kept constant. Advantageously, when the cutting tool is connected to the cutting tool carrier element, this provides precise chip removal machining by means of the adjustment device. If it is designed as a reduction gear, the self-locking provided in this way can in particular be achieved by means of the gearing of the drive unit, in particular of the planetary or spur gears.

According to a further embodiment of the adjustment device, the motion converter has a drive element which, in the drive state of the motion converter, is movable about the axis of rotation and can engage with a drive element guide of the cutting tool carrier element, the drive element of the cutting tool carrier element The orientation of the guide is different from the axis of rotation and the cutting tool carrier element has a drive element guide. This provides a particularly space-saving eccentric mechanism, which also enables particularly robust adjustment movements. Preferably, the axis of rotation is aligned with the longitudinal axis, thus saving more installation space volume in the axial direction. The drive element is preferably shaped as an axial projection (eg of a journal, preferably of a cylindrical journal) of the coupling element, which is mounted rotatably relative to the base body and/or the housing of the adjustment device, and which can form, for example, a circle Disc-like shape, the coupling element is mounted, for example, on a rolling element or a sliding body so that it can be rotated, for example, relative to the longitudinal axis. This is a particularly cost-effective and mechanically robust measure. The drive element can also be referred to as an eccentric pin. Preferably, the drive element guide is oriented transversely with respect to the longitudinal axis. The drive element guide is shaped as a recess (preferably of the longitudinal groove) of the cutting tool carrier element, into which the drive element engages. This is a particularly cost-effective and mechanically robust measure, especially with regard to the interaction with the drive elements. For example, transverse to the longitudinal axis may mean that the orthogonal projection of the drive element guide on a plane of projection oriented perpendicular to the longitudinal axis has a larger area than the orthogonal projection of the drive element guide on a plane of projection oriented parallel to the longitudinal axis . Preferably, the drive element guide is radial with respect to the longitudinal axis. Preferably, the motion sensor element has a recess for frontally and/or non-frontally receiving the drive element. Preferably, the coupling element is connected in a rotationally fixed manner to a moving element of the drive unit, wherein the moving element may be a gear shaft, in particular a gear output shaft, of a gearbox of the drive unit, in particular of a planetary or spur gear, and/or the motor shaft, in particular the pinion, of the motor of the drive unit, in particular of the electric motor. Thereafter, the drive unit can rotationally drive the coupling element to move the drive element about the longitudinal axis, ie at a non-zero distance radially from the longitudinal axis, and in a preferably circular path about the longitudinal axis.

According to another embodiment of the adjustment device, the motion converter is mounted on the bearing seat and the drive unit is reversibly and detachably connected to one side of the bearing seat. This measure provides a particularly simple assembly or disassembly of the adjustment device. In the bearing housing, in particular the coupling element with the drive element, in particular in an axially projecting manner (eg of a journal, preferably of a cylindrical journal), can be arranged on a rolling element bearing or on a sliding element bearing. In particular, a mounting plate and/or a mounting strut of the gearbox of the drive unit (in particular of a planetary gearbox or spur gearbox) can be arranged on the bearing seat, the mounting strut being connected to the motor (preferably of an electric motor) of the drive unit . Preferably, the bearing block is non-rotatably connected to the housing and/or the base body of the adjustment device.

According to another embodiment of the adjustment device, at least one sliding element is provided for sliding in and/or on the drive element guide, and the drive element is operatively connected to the sliding element. This provides optimized measures for sliding in the drive element guide, which in particular increases the efficiency and thus the efficiency of the motion converter and thus the adjustment device. Preferably, the sliding element is in the shape of a slide, in the case of the drive element guide in the form of a longitudinal groove, the geometry of the slide is adapted to the shape of such a groove, which further reduces the frictional resistance. Preferably, the sliding element has a groove for receiving the drive element. Preferably, the sliding element is shaped such that the maximum free sliding distance of the sliding element in the sliding direction of the drive element guide (in particular of the longitudinal groove) is less than the length of the sliding element measured radially. This measure provides particularly stable guidance for the sliding element in the drive element guide.

According to a further embodiment of the adjusting device, the drive element is mounted in and/or on the sliding element of the rolling element bearing and/or the sliding element bearing. This further increases the efficiency of the motion converter and thus the adjustment device, since according to this further embodiment the friction between the sliding element and the driving element is reduced. If the sliding element is mounted on the rolling element, the sliding element is preferably mounted by means of at least one needle bearing and/or at least one ball bearing. This is a particularly useful friction reduction measure.

According to another embodiment of the adjustment device, the circuit carrier element is connected in a rotationally fixed manner to a base body of the adjustment device, which is rotatable about the longitudinal axis, the base body having a connection for connection to the tool spindle. This further increases the compactness of the adjustment device, since the base body is used on the one hand to fasten the circuit-carrying element and, on the other hand, to connect it to the tool spindle, so that when the base body rotates, the circuit-carrying element acts as the base body or the tool spindle on the other hand. rotation speed. The rotationally fixed connection can be realized directly or indirectly. If implemented directly, the circuit-carrying element is connected directly to the base body in a rotationally fixed manner, for example by means of a screw element, wherein at least one screw for fastening the circuit-carrying element is arranged in the thread of the base body. If implemented indirectly, the circuit-carrying element is connected in a rotationally fixed manner to a housing different from the base body, and the housing is connected in a rotationally fixed manner to the base body, at least one screw for fastening the circuit-carrying element is arranged in the thread of the housing . The connecting part is particularly designed for connecting the base body to the anti-rotation device and/or the tool, thus for connecting the adjustment device to the anti-rotation device and/or the tool, for the axial pretensioning of the base body.

According to another embodiment of the adjustment device, the drive unit is arranged axially. This reduces, in a particularly advantageous manner, imbalances that can be induced by the drive unit when the adjustment device is rotated about the longitudinal axis. Further, in the case of one or more lubricants, which may be included in the drive unit to reduce friction of relatively movable components, the centrifugal effect of these is avoided, which improves the use of the drive unit life, thereby increasing the service life of the adjustment device. The relatively movable components can be, for example, the motor shaft of the electric motor of the drive unit and the corresponding bearing and/or the gear shaft of the gear box of the drive unit and the corresponding bearing (eg planetary gearbox or Spur Gearbox) Two or more meshing gears of a gearbox. Thereafter, it is particularly preferred that the longitudinal axis is aligned with the motor shaft of the motor of the drive unit (in particular of an electric motor) and/or the longitudinal axis is aligned with the gear output of the gearbox of the drive unit (eg of a planetary gearbox or spur gearbox) axis aligned.

According to another embodiment of the adjustment device, the drive unit and the motion converter are interconnected to form a first assembly, which can be axially dismantled or axially mounted independently of the circuit-carrying element. This improves the dismountability (eg in the case of maintenance) and the installability (eg in the case of assembly) of the adjustment device, since the time required in each case is reduced and at the same time the pre-assembly of the first component become possible. Thus, the drive unit, especially if it comprises gears, can be reversibly and releasably fastened to the bearing housing by means of at least one threaded element, wherein the motion converter is rotatably mounted to the bearing housing, so that the drive unit and the motion converter are rotatably mounted on the bearing housing. The bearing housings are connected to each other to form an axially removable or axially installable first component. Being axially removable or axially installable, the first component is particularly accessible from one side, eg the front side of the adjustment device, which further contributes to the ease of removal or installation. Axial removal or installation independently of the circuit-carrying element means in particular that the circuit-carrying element remains in and/or on the housing or base body of the adjustment device when the first component is removed or installed.

According to another embodiment of the adjustment device, the drive unit, the motion converter, the cutting tool carrier element and the circuit carrier element are interconnected to form a second axially removable or axially mountable assembly. This further improves the disassembly (eg in the case of maintenance) and the mountability (eg in the case of assembly) of the adjustment device, since the time required in each case is reduced and at the same time the pre-assembly of the second component become possible. Thus, the drive unit (especially if it comprises a gear) can be reversibly releasably fastened to the bearing housing by means of at least one threaded element, wherein the motion converter is rotatably mounted to the bearing housing for the drive unit and the motion converter The device can be assembled by at least one threaded element to form an axially removable or axially mountable first component. The drive unit and the motion converter are interconnected by means of a bearing seat to form an axially removable or axially mountable first assembly, and the bearing seat is reversibly releasably fastened (in particular by at least one threaded element) to the In and/or on a housing of the adjustment device, and the housing has a sliding surface for sliding the cutting tool carrier element, and the cutting tool carrier element is reversibly axially connected to the housing (in particular by means of at least one threaded element) The releasably connected housing cover locks, for example, so that the second component is formed in this way. Being axially removable or axially installable, the second component is particularly accessible from one side, eg the front side of the adjustment device, which further contributes to the ease of removal or installation.

According to a further embodiment of the adjustment device, the circuit carrier element is designed for data communication with a drive unit on one side remote from the circuit carrier element. This increases the ease of assembly and disassembly, since, for example, the drive unit, which is part of the first and/or second assembly, can be detached or connected particularly easily from the circuit-carrying element. The fact that the circuit-carrying element is designed for data communication with a drive unit on one side facing away from the circuit-carrying element preferably means that at least one contact-type means for connecting to a conductor arrangement, in particular of a multi-core power cable, is provided. The insertion point, the conductor arrangement is preferably connected to the printed circuit board of the electric motor of the drive unit.

According to a further embodiment of the adjustment device, the circuit-carrying element has a functional surface for the circuit-compatible component, the functional surface facing away from and/or towards the cutting tool-carrying element. In the case of facing away from the functional surface, the circuit-carrying element can be arranged particularly advantageously close to the cutting tool-carrying element, since when the circuit-carrying element is or is to be fitted with a component of at least one electronic control circuit according to the circuit, the functional surface in the fitted state has At least one boost. In the case of a functional surface facing the functional surface, the risk of damage associated with the assembly is minimized because it is being assembled with the functional surface facing the assembler so that the assembler can monitor the assembly accordingly.

According to another embodiment of the adjustment device, the data line arrangement is provided for data communication with the drive unit, and the surface area facing the drive unit is at least partially facing the data line arrangement. This provides a particularly simple structure of the adjustment device. Preferably, the data conducting means are designed as a multi-core power cable, in particular one of a flat design, which passes through the recess of the circuit-carrying element. One end of the data line arrangement is preferably connected in the sense of a plug contact to the circuit carrying element, and the other end of the data line arrangement is preferably connected in the sense of another plug contact to a second circuit carrying element, the second circuit carrying element preferably The ground has power electronic components or corresponding designed circuits.

According to another embodiment of the adjustment device, a measuring device adjacent to the circuit-carrying element is provided for measuring the adjustment distance that can be assigned to the adjustment movement, and the circuit-carrying element is designed to provide a control signal on the basis of the measurement data acquired by the measuring device . This is advantageous because it is possible to check whether a predefined adjustment movement is maintained, especially with regard to tool wear, especially in the area of one or more cutting edges. Preferably, the measurement device comprises electronic data processing means for processing measurement data acquired by the measurement device, according to which the circuit-carrying element conforms or can be configured to conform to the circuit. Preferably, the measuring device comprises a displacement measuring device designed to detect displacement according to inductive and/or resistive and/or capacitive and/or optical principles. Even more preferably, the cutting tool carrier element has at least one measuring scale and the base body and/or the housing of the adjustment device has sensors capable of detecting the measuring scale, and vice versa. With regard to the base body and/or housing of the adjustment device, the cutting tool carrier element is mounted in such a way that the adjustment movement is possible.

According to another embodiment of the adjustment device, the drive unit comprises a toothed gear and an electric motor operatively connected to the toothed gear, wherein the gear shaft of the toothed gear can be meshed with the motion converter, and the displacement carrier element is arranged with the The gear axis is vertical, and the gear axis can be associated with the gear shaft. This is a particularly advantageous way, since the gear transmission can provide many different gear shafts (especially in the form of gear output shafts) at a predefined drive speed of the motor shaft of the electric motor, depending on the number, arrangement or size of the respective gears. For the speed, the gear transmission can be planetary gear transmission and/or spur gear transmission. The fact that the gear lever carrier element is arranged perpendicular to the gear axis can also reduce the installation space volume, eg by arranging the normal vector of the surface portion of the gear lever carrier element parallel to the gear axis.

According to another embodiment of the adjustment device, it comprises a coolant channel system in communication with the coolant channel system of the cutting tool carrier element, and wherein the circuit carrier element is arranged adjacent to the at least one coolant channel system. This optimizes the adjustment device for increasing the service life of the cutting tool, because the cutting tool can be cooled in the chip-cleared state by means of the two coolant channel system, and the cleared chips can be removed by flushing the two coolant channel system with coolant. transport away (eg, inside walls of holes). Preferably, the coolant channel system of the cutting tool carrier element comprises coolant channel openings to enable coolant to leave the cutting tool carrier element. Preferably, sealing means are provided for sealing the interface between the cutting tool carrier element and the housing and/or base body of the adjustment device to avoid escape of coolant, relative to the housing and/or base body, relative to which the cutting tool carrier element can or move ground fixed.

According to another embodiment of the adjusting device, it is designed to be connected to the tool spindle. In this way, the adjustment device can advantageously be connected to the tool spindle, so that the rotational movement of the tool spindle can in this way be transmitted to the adjustment movement and thus to the cutting tool carrier element. Preferably, the adjustment device has a hollow shank cone for connection to the tool spindle or tool spindle. This is a particularly practical measure, which provides for non-positive and positive connections to correspondingly shaped tool spindles.

According to another embodiment of the adjustment device, it comprises a cutting tool which is reversibly and releasably connected to the cutting tool carrier element in an operable manner so that the cutting tool performs an adjustment movement in the activated state of the drive unit, wherein the cutting tool The tool has at least one cutting edge for chip removal. This advantageously provides an adjustable cutting tool, which can be driven in rotation about the longitudinal axis at relatively high speeds while having a compact design, since the adjustment device does not induce unbalance, or at least reduces the extent of the unbalance. According to this further embodiment, the adjustment device is preferably designed as an end face top and/or a drilled top. The cutting tool may preferably be a cutting tool, a drilling tool, a milling tool or a reaming tool or the like.

Detailed ways

As shown in FIGS. 1 to 5 , the same, similar or similarly acting elements are denoted by the same reference numerals, and repetitive descriptions of these elements are partially omitted in the following description to avoid repetition.

FIG. 1 shows a schematic perspective view of an adjustment device 1 according to one embodiment, as seen along the right obliquely upper line of sight of the adjustment device 1 . The adjustment device 1 is rotatable relative to the longitudinal axis 2 in either direction of rotation 2a, so that when the cutting tool is attached to the carrier plate 3 and the adjustment device 1 is rotated about the longitudinal axis 2 by means of a spindle not shown in the drawings The cutting tool rotates about the longitudinal axis 2. For this purpose, the adjustment device 1 is reversibly releasably fastened to the connecting portion 8 of the base body 12 with the spindle and the cutting tool is reversibly releasably fastened by means of a screw (not shown in the figure) by means of a tool holder (not shown in the figure). To the surface 4 of the carrier plate 3 provided with the grooves, the screws can engage with the threaded holes 5 of the carrier plate 3 . The grooves of the surface 4 engage in these corresponding grooves of the tool holder, so as to form a positive fit in a direction transverse to the running of the grooves and guide the positioning of the tool holder in a direction parallel to the running of the grooves. The carrier plate 3 is motor adjustable in direction 6, and therefore the cutting tool is also motor adjustable in direction 6, which is oriented radially with respect to the longitudinal axis so that the cutting tool moves about the longitudinal axis 2 according to the adjustment of the diameter of the flying circle , (for example) to machine a hole in the workpiece with a diameter corresponding to the diameter of the flying circle. The adjustment of the carrier plate 3 in one of the directions 6, i.e. forward and backward movement to adjust the pitch circle diameter, is decoupled from the rotation of the adjustment device 1 about the longitudinal axis 2, so that the pitch circle diameter is independent of the speed of rotation, wherein the rotation The speed can be specified as the rotational speed at which the adjustment device 1 rotates about the longitudinal axis 2 . The maximum adjustment distance of the carrier plate 3 in one of the directions 6 is, for example, 0.25 mm measured transversely to the longitudinal axis 2 . However, different adjustment amounts of the carrier plate 3 are also conceivable and possible.

In FIG. 1 it can be observed that the carrier plate 3 has a hole 7 connected to the coolant channel system, which will be discussed in more detail with reference to FIG. 3 . The hole 7 also serves as an anchor point for the anchor portion of the tool holder, which is biased and locked in a state where the pin 7 a is inserted into the hole 7 .

1 also shows that the carrier plate 3 protrudes from the opening 9a of the cover plate 9, so that the opening 9a forms a radial stop for the carrier plate 3 along the wall of the cover plate 9, wherein the wall of the cover plate 9 delimits the carrier plate 3. The cover plate 9 is in threaded engagement with the housing 11 having corresponding threads by means of threaded bolts (not shown in the figures), which are inserted or can be inserted into the holes 9b of the cover plate 9 so that the cover plate 9 is centered and relative to the longitudinal axis 2 Tangential locking as well as axial locking of the carrier plate 3 (the illustration of the same hole 9b opposite the visible hole 9b is obscured by the illustration of the carrier plate 7 and this hole 9b can be seen in the plan view shown in Figure 2). A jacket ring 10 consisting of an aluminium alloy (in each case glass or steel instead of an aluminium alloy is conceivable and also possible) is axially prestressed between the housing 11 and the cover plate 9, which is gas-tight The transition area between the cover plate 9 and the housing 11 is sealed.

The cover plate 9 and the housing 11 are screwed to the housing 11 with corresponding threads by means of other, larger threaded bolts not shown in the figures, which are inserted or can be inserted into the corresponding holes 9c of the cover plate 9 so as to pass through this. The assembly is formed in such a way that it can be removed or installed axially by loosening or tightening the threaded bolts (wherein all the holes 9c are shown in the plan view in Figure 2). In this way an assembly is formed, which can be axially dismantled or mounted axially by loosening or tightening the threaded bolts, and comprising the carrier plate 3, the cover plate 9, the grommet ring 10 and the housing 11 and together (in FIG. 1 ). not shown) a motor adjustment mechanism, and the motor adjustment mechanism is attached to the housing 11 . Referring to Figure 3, the motor adjustment mechanism is described in more detail.

The casing 11 is provided with threaded holes 11a for fastening threaded bolts in the circumferential direction. If necessary, the threaded bolts are used to compensate the unbalance of the adjustment device and can be screwed into the threaded holes 11a at different depths to realize the adjustment device 1. The center of gravity is correspondingly positioned on the longitudinal axis 2 .

The housing 11 is connected to the base body 12 of the adjustment device 1 by threaded bolts which are arranged or can be arranged partly through corresponding holes of the base body 12 and wherein the housing 11 has corresponding threads.

FIG. 2 shows a schematic view of the adjustment device 1 , which is a front view viewed in the direction of arrow II in FIG. 1 . FIG. 2 particularly clearly shows that the direction 6 is oriented radially with respect to the longitudinal axis 2 .

FIG. 3 shows a cross-sectional view of the adjustment device 1 in FIG. 1 according to section line III in FIG. 2 , viewed in the direction of the arrows assigned to section line III in FIG. 2 . In Figure 3, the internal structure of the adjustment device 1 is particularly clear. FIG. 3 shows that the electric motor 13 is cantilevered inside the adjustment device 1 . The electric motor 13 is further arranged about the longitudinal axis 2 so that the electric motor 13 is substantially (in the case of rotational symmetry of the electric motor 13 ) balanced when the adjusting device 1 is rotated about the longitudinal axis 2 . This may also be referred to as the axial arrangement of the electric motor 13 . When the electric motor 13 is started, the pinion 13a of the electric motor 13 rotates about the longitudinal axis 2 (eg by current flowing through its stator windings, not shown, for example by means of an inductive device, not shown, causing the pinion 13a to rotate about the longitudinal axis 2) is connected to the motor shaft of the electric motor 13 and is aligned with the longitudinal axis 2 . The pinion gear 13a is meshed with the multi-stage spur gear 13b to reduce the relatively high (eg, 1000 rpm) rotational speed of the pinion gear 13a to the relatively low (eg, 1 rpm) rotational speed of the output shaft 13c of the spur gear 13b Rotating speed. Here, it is expressly stated that the electric motor 13 comprising the pinion 13a forms a drive unit with a spur gear 13b comprising a gear output shaft 13c.

The gear 13b is connected to the bearing cap 15 by means of screws 14, and the gear 13b is screwed to the electric motor 13 outside the area of the pinion 13a so that it cannot rotate. The output shaft 13c is arranged to pass through the bearing cover 15 and is non-rotatably connected to a journal carrier wheel 16 which is rotatably mounted in the bearing cover 15 about the longitudinal axis 2 by means of rolling ball bearings 17 . The radially inner ring 17a of the rolling ball bearing 17 is axially preloaded by a threaded ring 17b, which is threadedly connected to the journal bearing wheel 16, so that the ring 17a is pressed against the radially protruding bearing of the journal bearing wheel 16. on the stop. The radially outer ring 17c of the rolling ball bearing 17 is axially preloaded against the housing 11 by a retaining plate 17d, which is screwed to the housing 11 . In order to provide a defined preload, the retaining plate 17d is spaced from the bearing cap 15 by a tangential circumferential gap. The retaining plate 17d is then used to secure the connection of the housing cover 15 to the housing 11 so that the journal carrying wheel 16 mounted therein is connected to the housing 11, which in turn can be driven by the electric motor through the gear output shaft 13c 13 drives. In this driving state, the eccentric pin 18 integrally connected to the journal carrier wheel 16 runs in a circular orbit around the longitudinal axis 2 because the axis of rotational symmetry of the eccentric pin 18 is offset radially relative to the longitudinal axis 2 .

The electric motor 13, the gear 13b, the bearing cap 14 and the journal carrier wheel 16 form another assembly, which passes through the printed circuit board 200, in particular since it is disclosed that the gear 13b and the journal carrier wheel 16 are respectively connected to the bearing cap 15, So that this assembly can be installed or removed axially without removing or installing the printed circuit board 200 for this purpose (the printed circuit board will be described in more detail below). This is achieved in particular by tightening or loosening screws, which are screws connecting the retaining plate 17d to the housing 11 in a reversible and releasable manner.

The eccentricity, ie the radial distance between the rotational symmetry axis of the eccentric pin 18 and the longitudinal axis 2, is exemplarily 0.25 mm, whereby the adjustment device 1 may be referred to as a micro-adjustment device or a micro-adjustment head. The cylindrical eccentric pin 18 is rotatably mounted in the slide 20 via a needle bearing 19 . The slider 20 is slidably mounted in the longitudinal groove 21 of the carrier plate 3 which extends perpendicular to the drawing plane in FIG. 3 . When the eccentric pin 18 is driven, the slider 20 slides along the longitudinal groove 21 due to the eccentricity of the eccentric pin 18 relative to the longitudinal axis 2, and thus the slider 20 slides along the longitudinal groove 21 due to the eccentricity relative to the longitudinal axis of the pinion 13a , however, due to the positive fit shown in FIG. 3 , after the gear output shaft 13c performs one rotation around the longitudinal axis 2, the journal carrying wheel 16 also performs one rotation around the longitudinal axis 2, and the casing Between the body cover 9 and the housing ring 6, the carrier plate 3 moves in translation in direction 6 relative to the longitudinal axis 2, and thus in direction 6 relative to the longitudinal axis of the pinion 13a. In order to set a certain displacement of the carrier plate 3 in one of the directions 6, the gear output shaft 13c is therefore part of one revolution around the longitudinal axis through the gear 13b and the electric motor 13, this displacement in the unpowered state of the electric motor 13 is locked due to the self-locking of the gear 13b.

FIG. 3 also shows particularly clearly a printed circuit board 200 with a control circuit which includes electronic components mounted on a functional surface 210 in the adjustment device 1 facing away from the carrier board 3 in order to operate in one or more The electric motor 13, and thus the pinion 13a, the journal carrier wheel 16, and ultimately the carrier plate 3, are controlled on the basis of further measurement signals, which may also be referred to as input signals. (The measurement signal may correspond, for example, to information about a predetermined hole diameter or a deviation of a predetermined hole diameter.) (The measurement signal may, for example, correspond to information about a predetermined hole diameter or a predetermined hole diameter.) information on the deviation of the diameter of so that in the absence of the control circuit, (as long as the printed circuit board 200 is formed rotationally symmetrical) the rotation of the printed circuit board 200 relative to the longitudinal axis 2 is balanced. Since the printed circuit board 200 is connected in a rotationally fixed manner to the housing 11 by means of locking screws 240 (shown in the top view in FIG. 4 ), in the case of rotation of the adjustment device 1 about the longitudinal axis 2 , the printed circuit board 200 is rotated about the longitudinal axis 2, the screw 240 is arranged on the partial sleeve 240a, and the printed circuit board 200 is correspondingly arranged on the sleeve 240a. The screw 240 is threaded into the housing 11 .

The printed circuit board 200 or its control circuit can be directly or indirectly connected to another printed circuit board 300 by means of data communication through conductive means or other similar means not shown. The power electronic components shown, whereby part of the conducting means can pass through the holes 230 so that they can be connected to the plug contacts towards the side of the carrier board 3 , ie the side opposite the functional surface 210 . Thus, the printed circuit board 300 is electrically connected to the stator windings of the electric motor 13 .

FIG. 3 also shows particularly clearly the first coolant channel system formed in the housing 11 and the base body 12 , which system consists of coolant ducts 400 arranged in the connecting portion 8 and the base body 12 parallel to the longitudinal axis 2 , Where the pipes are screwed into the base body 12 in the end region, the passage holes 410 of the base body 12 are arranged at an angle to the longitudinal axis 2 , ie not parallel, the passage holes 420 of the base body 12 are arranged parallel to the longitudinal axis 2 , the housing 11 The coolant ducts 430 are partially arranged in the duct holes 40 parallel to the longitudinal axis 2, the channel holes 440 of the housing 11 are arranged parallel to the longitudinal axis 2, the coolant ducts 430 are partially inserted into the channel holes 240 and arranged parallel to the longitudinal axis 2 with the passage holes 440 of the housing 11 arranged parallel to the longitudinal axis 2 and a second coolant passage system is formed on the side of the carrier plate and the second coolant passage system is arranged by the passage holes 450 of the carrier plate 3 In the carrier plate 3 and at an angle to the longitudinal axis 2 . Therefore, the two coolant channel systems are connected to each other in a communicative manner, so that the coolant entering the coolant channel 400 flows out of the channel holes 450 and in this way floods the holes 7 in a specific area, after which the coolant is supplied to the workpiece Machining tool and/or hole wall not shown.

Figure 3 shows particularly clearly that in the hole 500 of the connecting part there is arranged a bolt 0510, the connecting part 8 transverse to the longitudinal axis 2, which can form a positive engagement with the spindle adapter element so that the torque can be transmitted from the tool spindle to the adjustment device 1.

Figure 3 also particularly clearly shows the axial length denoted by the reference numeral 1000, measured from the base body 12 to the carrier plate 3, which is 3.4 times greater than the axial length denoted by the reference numeral 1100 , the axial length denoted by the reference numeral 1100 is the dimension of the connecting portion 8 , which corresponds to the inverse measure of the compactness of the adjustment device 1 . Smaller values for this factor (<3.4) are also conceivable and possible, eg, 3.3, 3.2, 3.1, 3.0, 2.9, 2.8, 2.7, 2.6, 2.5, 2.4, 2.3, 2.2, 2.1, or 2.0.

Furthermore, as can be seen from Figure 3, the length 1000 is independent of the dimensions of the printed circuit board 200, since the latter is axially shorter than the electric motor and is arranged tangentially around the latter.

FIG. 4 is a sectional view of the adjustment device of FIG. 1 according to section line IV in FIG. 3 , viewed in the direction of the arrow assigned to section line IV in FIG. 3 . In FIG. 4 the printed circuit board 200 is particularly clearly visible. Thus, among other things, the control circuit is formed by the interconnection of electronic components 500, 510, 520 and 530 by means of conductive tracks extending within the printed circuit board 200, the component 530 being designed for connection to another printed circuit board The electronic connector enables the control circuit to receive the input signal and output the corresponding output signal. After the output signal is calculated by the control circuit, the carrier board 3 is adjusted in a predetermined manner. As shown in FIG. 4 , the two surface points 600 and 610 of the surface 220 are connected by a connecting line 620 . The connecting line 620 intersects or runs through the electric motor 13 . As shown in FIG. 4 , the bore 230 in which part of the electric motor 13 , pinion 13 a and gear 13 b is arranged is annularly closed by an annular rim 630 , the longitudinal axis 2 being the bore 230 or the axis of rotational symmetry of the rim 630 . It is apparent that the center of the hole 230 (ie, the circle defined by the rim 630 ) is associated with the two-dimensional barycentric coordinates of the printed circuit board 200 (defined by the outer butterfly rim 640 ). The barycentric coordinate is also geometrically a point on the longitudinal axis.

FIG. 4 also shows that the housing 11 has threaded holes 1500 a into which corresponding threaded bolts can be threaded in their respective threaded regions to connect the base body 12 and the housing 11 .

FIG. 5 shows a schematic view of the adjustment device in FIG. 1 , which is a rear view viewed in the direction of arrow V in FIG. 1 .
